ROBERT FARIES, OF DECATUR, ILLINOIS.

SPRING-MOTOR.

SPECIFICATION forming part of Letters Patent No. 404,526, dated June 4,1889.

I Application filed June 6, 1888. Elerial No. 27 6,177. (No model.)

To aZZ whom it may concern:

Be it known that I, ROBERT FARIES, a citizen of the United States,residing at Decatur, in the county of Macon and State of Illinois, haveinvented certain new and useful Improvements in Spring-Motors; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My motor is especially designed to rotate devices for displaying goods;and the novelty exists in the speed-regulator and the generalarrangement of parts, as hereinafter set forth.

In the drawings accompanying and forming a part of this specification,Figure 1 represents the working parts of my device. Fig. 2 is a faceview of the main gear-wheel, showing the main shaft in section with thedrive-ratchet mounted thereon; and Fig. 3 is an elevation of the incasedworks, with the spring indicated by dotted lines and the upper portionof the casing partly broken away to show the load-supporting shaft andto indicate by dotted lines its connection with the drive-shaft of themotor.

The bed-plate A has lateral extensions B, that are provided withthreaded levelingbolts 1). It also has lugs D, that are provided withholes (I, through which securing-screws d extend, as shown in Fig. 3.The frame 0 provides bearings for the several parts of the motor, andthe screws 0, passing through the foot-like extensions 0, secure theframe to the bed-plate. The casing A rests on the bed-plate and incasesthe works. The central tubular upward extension A" provides at its top abearing for the load-supporting shaft y. The main shaft E has thespur-wheel E, the spring F, and the ratchet-wheel o rigidly attachedthereto. The spur wheel G is mounted loosely on the main shaft, and isrecessed in one face to receive the ratchet- Wheel. The drum e and hook6 provide a point of attachment for a duplicate spring in case morepower is needed. WVheel G conveys motion to pinion H on horizontal shaftH. Crown-wheel H on the same shaft conveys motion to a pinion onvertical drive-shaft I, and-said drive-shaft has a bearing in the top offrame A at c, and is preferably provided with the conical depression 2'.Shaft y is preferably provided with a conical lower termination adaptedto the conical depression in the drive-shaft, and it extendssufficiently high to insure stable equilibrium to the encircling weightthat it is designed to carry.

An obvious modification of the conical frictional connection of thevertical shafts will exist in opposing plane surfaces, and, if desired,the load may receive motion from shaft y by a frictional connection, thesame as specified. The pressure of shaft y on shaft I will developsufiicient friction to'cause the load to revolve, and a temporarystoppage or reversal of the direction of the loads rotation by externalforce will not injuriously affect the motor. Sleeve t screws into theeasing and provides abearing for Winding-crank n, which is provided onits inner end with a drive-pinion s, that meshes with wheel E, as shownin Fig. 1. The spring is wound by the crank, and its force is exerted onthe primary wheel through pawls to, which are held in contact with theratchet by springs x.

The governor or speed-regulator comprises the Wheel I on shaft 1,meshing with a pinion on shaft K, the wheel K on shaft K, meshing withpinion r on shaft q, cross-head p on shaft q, rods n, suspended from thecross-head and weighted at n, and the annular band M loosely embracingthe rods. Plate L provides bearings for shaft K and q, and plate Lfurnishes a bearing for the lower end of shaft q.- As the head rotates,the rods are swung outward at their lower ends by centrifugal force, andafter a certain speed is developed press against the band and developfriction in a degree exactly proportionate to the surplus power to beneutralized.

I claim as new and desire to secure by Let ters Patent 1. Amotor-regulator comprising the shaft q, carrying cross-head p, rods a,suspended vertically from the cross-head, and annular band M, encirclingthe rods below their .points ROBERT FARIES.
